Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed September 10, 1912. "serial No. 719,601.

To all whom it may concern:

Be it known that I, MEYER KEILSON, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and useful Improvement in Alarm Devices, of which the following is a full, clear, and exact specification.

'This invention relates to a class of devices adapted to be used especially in conjunction with drip pans.

My invention has for its object primarily to provide a form of device designed to be applied upon a pan, or similar receptacle when used to receive the drip water from a refrigerator, ice chest, or the like, and which is adapted to automatically sound an alarm when the receptacle is sufiiciently filled with water so as to be emptied in due time to prevent the receptacle from overflowing.

Another object of the invention is to provide a spring actuated clamp which serves 4 is a section taken on the line III-III of a topermit the device to be readily attached, or detached from the receptacle whereby the device'may be used insuccession upon several receptacles, and a further object of the inventionis to provide an alarm device of a compact, durable, and efiicient form.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, the said invention being more fully described herein after, and then pointed out in the appended claims. a

In the drawing, Figure 1 is a fragmentary view of a drip pan with one form of my improved alarm device applied thereto. Fig. 2 is an end view of the device, part of which is broken away. Fig. 3 is a section taken on the line II-II of Fig. 1, and Fig.

Fig. 1.

The alarm device 10 is adapted to be detachably applied upon any suitable form of pan, or receptacle, as 11, which may be used to receive the drip water'from a refrigerator, ice chest, or the like, and said device has a supporting member, orstraddle bar 12 composed of two arms 13 and 14: which are spaced apart in parallel relation so as to provide a slot 15 therebetween for reception of the wall of the receptacle over which said arms are disposed when the device is applied th e n, a wi l be here n er m re f l y described. Each of the arms 18 and 1 1 are substantially U-shaped, as shown in Fig. 3, whereby recesses 16 and 17' are provided. Upon the top of both of the arms 13 and 1 1 is an integrally formed transverse bar 18 which is of a length to extend some distance beyond the arms 13 and 14, and said transverse bar is also preferably U-shaped whereby a recess '19 is formed.

Serving as a means to permit the supporting member, or straddlebar 12 to be yieldingly held upon the wall of the receptacle,

'in order to permit the device to be readily Both of the pins 22 and 23 are movably guided through openings in the transverse wall of the U-shaped arm 14 of the straddle bar, and encircling each ofthe pins between said transverse wall and'the elongated plate 21 is a spiral spring 24 and 25. The springs 24: and 25 normally serve to force the elon-' gated plate 21 of the clamp toward the arm 13 of the straddle bar soas to yieldingly engage the opposed surface ofthe wall of the receptacle when the straddle bar is disposed thereover, as shown in Fig. 1'.

To the transverse wall of the U- haped arm 13 of the straddle bar is secured an alarm 26 which is preferably of the form'of a bell of the well known type which isad'apted to be wound by rotating a part of its cas ing, and which is sounded by moving a stem, as 27, which projects outwardly of the sta tionary part of the casing of the alarm. The

stem 27 is of sufficient length to extend through an opening in the transverse wall of the top U-shaped bar 18 of the straddle bar, and said stem is adapted to bev moved in a direction inwardly of the casing of the alarm for sounding it by a spring controlled plate 28. The plate 28 is preferably seated in the recess 19 of the U-shaped bar 18, and has one of its. endspivoted, at

'29, at the free end of said U-shaped bar.

The plate 28 is of a length to extend some distance beyond the other end of the bar 18. Upon the top of the bar 18, and at its end to which is pivoted the plate 28, is held one end of a spring 30 which is curved so that its free end is in contact with the free end of fwiththe plate 28. The extension 3% will the plate 28, in order to normally serve to force said plate in contact with the stem 27 of the alarm.

Projecting from the end of the transverse U-shaped bar 18 opposite to the end to which 'isxpivoted the plate 28,: is a lever31. The

lever 31 is of a length to extend toward the center, or beyond the center of the receptacle, and at one end of said lever is held a float, as 32. The lever'31' is also pivoted, or fulcrumed intermediate its length, as at 33, to the U-shaped bar 18,wvher eby an exten sion 34 is provided and said extension'isv adapted to engage the spring controlled plate 28 t'or directing this plate upwardly so as to be free from engagement with the stem 27 of thealarm whenfthe float 32 is lowered inqthe receptacle, as" indicated by dotted lines at 35, when there is no liquid therein, or when it is only partially filled.

YW hen the receptacle is sufliciently filled with liquid whereby it should be emptied to avoid overflowing the float will. be carried uponthe surface of the liquid, and the lever 31 will be moved toa position in alinement thereby be freed from engagement with the {plate 28, and the tension of the, spring i will force said plate in a direction to engage ,.alarm of the device.

and move the stem 27 for sounding the In the foregoing."description, Ilhave em- "bodied the preferred form of my invention,

but Ido not Wish to be understood as limitfing myself thereto as I am aware that modifications may bemade therein without departing from the principle,'or sacrificing "any of the advantages of .this'invention,

therefore I; reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus :described my invention, I

' claimfas new and desire to secure by Letters Patent V H V 1. An alarm, compris ngtin combination,

a supporting member adapted to be at tached to a liquid containing vessel, a movable stem, a spring controlled movable plate inounted upon the said supporting member and adapted to normally hold said movable stem in operative position to sound said alarm, a lever pivoted at a point near one of its ends to the said supporting member, whereby the end of said lever will engage the said spring controlled movable plate to free said plate from contact with said movable stem when the opposite end of said lever is lowered, a float carried on said lever at its said opposite end and adapted to I swing the said end upwardly, thereby allowing the spring controlled plate to descend into engagement with the movable stem of the alarm when the liquid in the vessel rises to a predetermined height.

2. An alarm, comprising in combination, a supporting member adapted to be attached to a receptacle, a movable stem adapted to sound said alarm, a spring controlled .movable plate mounted upon thesaid supporting member and adapted to normally hold said movable stem in operative position to sound said alarm, a lever pivoted at alarm.
